HYDROCARBON-BURN ER.

SPECIFICATION forming part of Letters Patent No. 559,670, dated May 5, 1896.

Application filed August 14, 1895. Serial No. 559,270. (No model.) I

To all whom it may concern/.-

Be it known that I, Tnonas J. BRoUeH, of Baltimore city, in the State of Maryland, have invented a new and useful Improvement in Hydrocarbon-Burners, of which the following is aspecification.

The object of my invention is to provide a hydrocarbon-burner for burning coal-oil or crude oil, either for heating or illuminating purposes,without the use of a wick, and which when used for heating purposes produces a blue blaze of the greatest heating capacity without smoking or depositing its carbon.

To this end it consists in the peculiar construction and arrangement of the parts of the burner, which. I will now proceed to describe.

Figure 1 is a side view, partly in section, of my improved burner. Fig. 2 is an underneath or inverted plan View of the deflector for the burner. Fig. 3 is a perspective View of the same. Fig. 4 is a vertical section of the burner-valve. Fig. 5 is a similar view showing a slight modification. Fig. 6 is a sec tion, and Fig. 7 a side View, of the burnervalve as constructed for mingling air with the oil-vapors. Fig. Sis a plan view of the slidevalve or cap, and Figs. 9 and 10 are respectively a sectional view and a plan View of a still further modification of burner-valve.

Referring to Figs. 1, 2, and 3, A is the oilpipe leading from the reservoir and terminating in a horizontal volute spiral coil B. D is a detachable deflector-plate for spreading the flame about the coil B and retaining the heat thercabout. This deflector consists of a central disk portion having three (more or less) radial tongues d, that project clownwardly through the central opening in the coil 13, and serve to hold the deflector in place. Said deflector also has an external ring or flange cl, connected at (Z to the central disk, and between which flange and the central disk are left segmental openings (1 through which the hot products of combustion may pass. The inner end of coil B extends downwardly at B and connects with the case 0 of the burner-valve. This case (see Figs. 4 and 5) is screw-threaded interiorly at its lower end to receive a screw-threaded plug 0, which is turned by a handle 0 to advance or withdraw the stem in the case. The case C is enlarged, or the stem C slightly reduced at its upper end a, to allow the oil from pipe I3 to pass around it, and the upper end of the case is formed with a conical seat a terminating with an outlet. The upper end of the valve stem has a pin a, which protrudes through the outlet in the case and has a shoulder (6 which when the valve is shut bears against and tightly fits with a ground joint against the conical surface of the seat a. This seat a? may have a single straight taper, as in Fig. 4, or it may have two different tapers at an angle, as in Fig. 5. In either case the pin a passes through the outlet in the case and guides the valve-stem and also regulates the size of the circular film of vapor, while the shoulder a tightly closes and cuts oit the escape of vapor by coming to a tight bearing against the conical seat a In Figs. 6, 7, and 8 I show a burner-valve for mingling air with the gas. The valvestem C has a slide-valve cap or section C concentrically arranged on top of its stem 6, and connected to it for a swiveling action by a circular groove e in stem e, and a pin e in the slide-valve cap 0 so that when G and e are turned C moves up or down without turning, being prevented from rotating in the case by a groove 6 receiving a pin e in the case. The stem 6 of the rotary plug and also the stem a of the slide-valve or cap G are provided with alined longitudinal openings c and h, which admit air centrally to the flame and take it through the side of the case at two points, one through an opening I)" in the slide-valve section, and b in stem 6 which register with a larger opening in the side of the case, this latter opening being long enough not to cut off the air as the slide-valve moves up or doign. The other opening I) receives its air through a slot Z1, extending about one-fourth around the case, so that it continues to receive air as the screwplug rotates in its adjustment. To pass the oil from pipe B to the outlet-opening in the case, the slide-valve section 0 is cut away on one side, as at a in Fig. 8.

As a further modification I may make the case with a cup-shaped upper end, as at f in Figs. 9 and 10, and form three (more or less) air-ducts 9 through the edge of the case, en-

with a spiral coil of pipe, and in which a marginal vertical flange d at the outer edge is connected to a smaller central disk D by radial arms (1 so as to leave segmental spaces (1 between, and the radial arms (Z are ex tended down in the center to form tongues d, that pass through the central opening in the coil and hold the cap or deflector against lateral displacement, so that the hottest proclucts of combustion pass up centrally to the disk D and are then deflected outwardly to the segmental openings (1 serving in such passage to heat the oil in the coils, which then are effectually heated to volatilize the oil and yet afford no obstruction to the draft. The burner cap or deflector, as composed of the disk I), marginal flange (Z, radial arms (1 and downwardly extending tongue (1, immediatelybelow the disk D, is all cast in one piece, and, as before suggested, is correlated to the coil in special combination. I am also aware that valves have heretofore been constructed in which a screw-plug has a reduced stem playing in the outlet-orifice and a shoulder behind. the stem that had sides parallel to the case and was adapted to come to a flat bearing against the case. In my invention the shoulder has its sides out of parallel with the sides of the case and does not come to a flat bearing; but the shoulder on the screw-plug is cut so as to cause its sharp edge only to bear against the conical seat of the case. This not only centralizes the screw-plug and its regulating-stem, but makes an absolutely tight fit that precludes the leaking of vapor past it.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a hydrocarbon-burner, the combination with a horizontal spiral coil having a cen tral opening and its end carried down and terminating in a subjacent burner-valve, of a burner cap or deflector consisting of a central v disk, a vertical marginal flange of larger di ameter, radial arms connecting it permanently to the central disk and having tongues extended downwardly below the central disk and fitting through the opening of the coil, whereby the coils are heated without interfering with the upward draft, and the cap is se curelybut removablyheld upon the coils substantially as and for the purpose described.

2. The air-mixing oihburner consisting of the screw-threaded case with openings 1) and b in its side, and a conical seat and outlet at its upper end; the screw-plug O with channeled stem 6 having peripheral groove 6', the slide-valve or cap-section C concentrically mounted on stem 6 and provided with longitudinally-channeled stem a, lateral openings b pin 6 and means for preventing it from rotating substantially as and for the purpose described.

3. The air-n1ixing oil-burner, consistin g of the screw threaded case with longitudinal opening b and transverse opening I) in its side and a conical seat and outlet at its upper end, the screw-plug O with channel Z), channeled stem c having peripheral groove 8, and opening Z), the slide-valve or cap-section C concentrically mounted on stem 6 and provided with longitudinally-channeled stem a, lateral opening b pin 6 and a sliding pin connection a 6* substantially as and for the purpose described.
